• get the path of moved directory/file (source path and destination path)

  - by Ghanshyam Rathod

  When one directory is moved to other destination path, then i want to log the entry of original source path and entry of the path where it moved. any command is already available ? or any other way of doing this task? Ex: D1 = /home/user/Documents/test D2 = /home/user/Documents/Data/test when i moved D1 directory to the destination path to D2 directory then i want to log, like "test" directory is moved from D1 to D2 path Thanks

• Anatomy of a .NET Assembly - PE Headers

  - by Simon Cooper

  Today, I'll be starting a look at what exactly is inside a .NET assembly - how the metadata and IL is stored, how Windows knows how to load it, and what all those bytes are actually doing. First of all, we need to understand the PE file format. PE files .NET assemblies are built on top of the PE (Portable Executable) file format that is used for all Windows executables and dlls, which itself is built on top of the MSDOS executable file format. The reason for this is that when .NET 1 was released, it wasn't a built-in part of the operating system like it is nowadays. Prior to Windows XP, .NET executables had to load like any other executable, had to execute native code to start the CLR to read & execute the rest of the file. However, starting with Windows XP, the operating system loader knows natively how to deal with .NET assemblies, rendering most of this legacy code & structure unnecessary. It still is part of the spec, and so is part of every .NET assembly. The result of this is that there are a lot of structure values in the assembly that simply aren't meaningful in a .NET assembly, as they refer to features that aren't needed. These are either set to zero or to certain pre-defined values, specified in the CLR spec. There are also several fields that specify the size of other datastructures in the file, which I will generally be glossing over in this initial post. Structure of a PE file Most of a PE file is split up into separate sections; each section stores different types of data. For instance, the .text section stores all the executable code; .rsrc stores unmanaged resources, .debug contains debugging information, and so on. Each section has a section header associated with it; this specifies whether the section is executable, read-only or read/write, whether it can be cached... When an exe or dll is loaded, each section can be mapped into a different location in memory as the OS loader sees fit. In order to reliably address a particular location within a file, most file offsets are specified using a Relative Virtual Address (RVA). This specifies the offset from the start of each section, rather than the offset within the executable file on disk, so the various sections can be moved around in memory without breaking anything. The mapping from RVA to file offset is done using the section headers, which specify the range of RVAs which are valid within that section. For example, if the .rsrc section header specifies that the base RVA is 0x4000, and the section starts at file offset 0xa00, then an RVA of 0x401d (offset 0x1d within the .rsrc section) corresponds to a file offset of 0xa1d. Because each section has its own base RVA, each valid RVA has a one-to-one mapping with a particular file offset. PE headers As I said above, most of the header information isn't relevant to .NET assemblies. To help show what's going on, I've created a diagram identifying all the various parts of the first 512 bytes of a .NET executable assembly. I've highlighted the relevant bytes that I will refer to in this post: Bear in mind that all numbers are stored in the assembly in little-endian format; the hex number 0x0123 will appear as 23 01 in the diagram. The first 64 bytes of every file is the DOS header. This starts with the magic number 'MZ' (0x4D, 0x5A in hex), identifying this file as an executable file of some sort (an .exe or .dll). Most of the rest of this header is zeroed out. The important part of this header is at offset 0x3C - this contains the file offset of the PE signature (0x80). Between the DOS header & PE signature is the DOS stub - this is a stub program that simply prints out 'This program cannot be run in DOS mode.\r\n' to the console. I will be having a closer look at this stub later on. The PE signature starts at offset 0x80, with the magic number 'PE\0\0' (0x50, 0x45, 0x00, 0x00), identifying this file as a PE executable, followed by the PE file header (also known as the COFF header). The relevant field in this header is in the last two bytes, and it specifies whether the file is an executable or a dll; bit 0x2000 is set for a dll. Next up is the PE standard fields, which start with a magic number of 0x010b for x86 and AnyCPU assemblies, and 0x20b for x64 assemblies. Most of the rest of the fields are to do with the CLR loader stub, which I will be covering in a later post. After the PE standard fields comes the NT-specific fields; again, most of these are not relevant for .NET assemblies. The one that is is the highlighted Subsystem field, and specifies if this is a GUI or console app - 0x20 for a GUI app, 0x30 for a console app. Data directories & section headers After the PE and COFF headers come the data directories; each directory specifies the RVA (first 4 bytes) and size (next 4 bytes) of various important parts of the executable. The only relevant ones are the 2nd (Import table), 13th (Import Address table), and 15th (CLI header). The Import and Import Address table are only used by the startup stub, so we will look at those later on. The 15th points to the CLI header, where the CLR-specific metadata begins. After the data directories comes the section headers; one for each section in the file. Each header starts with the section's ASCII name, null-padded to 8 bytes. Again, most of each header is irrelevant, but I've highlighted the base RVA and file offset in each header. In the diagram, you can see the following sections: .text: base RVA 0x2000, file offset 0x200 .rsrc: base RVA 0x4000, file offset 0xa00 .reloc: base RVA 0x6000, file offset 0x1000 The .text section contains all the CLR metadata and code, and so is by far the largest in .NET assemblies. The .rsrc section contains the data you see in the Details page in the right-click file properties page, but is otherwise unused. The .reloc section contains address relocations, which we will look at when we study the CLR startup stub. What about the CLR? As you can see, most of the first 512 bytes of an assembly are largely irrelevant to the CLR, and only a few bytes specify needed things like the bitness (AnyCPU/x86 or x64), whether this is an exe or dll, and the type of app this is. There are some bytes that I haven't covered that affect the layout of the file (eg. the file alignment, which determines where in a file each section can start). These values are pretty much constant in most .NET assemblies, and don't affect the CLR data directly. Conclusion To summarize, the important data in the first 512 bytes of a file is: DOS header. This contains a pointer to the PE signature. DOS stub, which we'll be looking at in a later post. PE signature PE file header (aka COFF header). This specifies whether the file is an exe or a dll. PE standard fields. This specifies whether the file is AnyCPU/32bit or 64bit. PE NT-specific fields. This specifies what type of app this is, if it is an app. Data directories. The 15th entry (at offset 0x168) contains the RVA and size of the CLI header inside the .text section. Section headers. These are used to map between RVA and file offset. The important one is .text, which is where all the CLR data is stored. In my next post, we'll start looking at the metadata used by the CLR directly, which is all inside the .text section.

Most Oracle software installers need assembler Assembler (as) is not installed by default on Solaris 11.      Find and install eg., # pkg search assembler INDEX ACTION VALUE PACKAGE pkg.fmri set solaris/developer/assembler pkg:/developer/[email protected] # pkg install pkg:/developer/assembler Assembler binary used to be under /usr/ccs/bin directory on Solaris 10 and prior versions.      There is no /usr/ccs/bin on Solaris 11. Contents were moved to /usr/bin 2. Non-interactive retrieval of the entire list of disks that format reports If the format utility cannot show the entire list of disks in a single screen on stdout, it shows some and prompts user to - hit space for more or s to select - to move to the next screen to show few more disks. Run the following command(s) to retrieve the entire list of disks in a single shot. format 3. Finding system wide file descriptors/handles in use Run the following kstat command as any user (privileged or non-privileged). kstat -n file_cache -s buf_inuse Going through /proc (process filesystem) is less efficient and may lead to inaccurate results due to the inclusion of duplicate file handles. 4. ssh connection to a Solaris 11 host fails with error Couldn't agree a client-to-server cipher (available: aes128-ctr,aes192-ctr,aes256-ctr,arcfour128,arcfour256,arcfour) Solution: add 3des-cbc to the list of accepted ciphers to sshd configuration file.

Any help with this it would be appreciated -sorry for my english Thank you

• Find directories that DON'T contain a file but YES another one

  - by muixca

  I have quite a large music collection and would like to find the directories in which I still have compressed files (*.rar) unprocessed. Hence looking for a command that lists directories in which i do NOT have *.flac or *.mp3 but YES *.rar present. Working off found examples in this post: Find directories that DON'T contain a file I tried: comm -3 \ <(find ~/Music/ -iname "*.rar" -not -iname "*.flac" -not -iname "*.mp3" -printf '%h\n' | sort -u) \ <(find ~/Music/ -maxdepth 5 -mindepth 2 -type d | sort) \ | sed 's/^.*Music\///' but don' work.

• Adobe Illustrator can't open SVG file

  - by themapguyde

  I have a generated SVG file which for some reason won't open in Adobe Illustrator when I serve the file content from my ASP.net application, but if I were to write this generated file directly to the file system from my ASP.net application, the file opens fine! I've put a zip of the two files here: http://dl.dropbox.com/u/1761973/Files.zip The zip has two files: Map.svg Test.svg Map.svg doesn't open in Illustrator, it shows up a Text Import Options dialog, and upon clicking OK, will show the XML content of the file. Test.svg opens fine in Illustrator. Doing a comparison of the two files yields NO DIFFERENCES whatsoever! There must be something different in these two files (caused by downloading the generated SVG from the web browser), but I have no idea what?

• Windows Server 2008 CMD Task Schedule not running

  - by Jonathan Platovsky

  I have a BAT/CMD file that when run from the command prompt runs completely. When I run it through the Task Scheduler it partially runs. Here is a copy of the file cd\sqlbackup ren Apps_Backup*.* Apps.Bak ren Apps_Was_Backup*.* Apps_Was.Bak xcopy /Y c:\sqlbackup\*.bak c:\sqlbackup\11\*.bak xcopy /y c:\sqlbackup\*.bak \\igweb01\c$\sqlbackup\*.bak Move /y c:\sqlbackup\*.bak "\\igsrv01\d$\sql backup\" The last two lines do not run when the task scheduler calls it. But again, work when manually run from the command line. All the local sever commands run but when it comes to the last two lines where it goes to another server then it does not work.

• FTP ASCII file from Windows to Mainframe (iSeries) — special characters

  - by MikeM

  I have a text file created on a Windows machine, the page coding used on the file is 1252 This file is then ftp'd to an iSeries machine for processing As far as I can see, it appears on the iSeries. It has a CCSID of 037. Sometimes this file contains French characters (e.g. é). When this happens, the FTP will fail with a truncation error as the french character gets converted to some extra junk: �. The file is fixed block so the line does get truncated due to the one character turning into 3. I can convert the French characters to characters without the accents before sending but would prefer to keep everything intact. So is there a way to retain them and send the file over properly? I'm very green on iSeries, mainly a Windows guy.

• Uninstalling MySQL for MariaDB Replacement on cPanel

  - by ImmortalFirefly

  Well the first part of my day was spent researching how to remove MySQL to install MariaDB and the second part of my day was spent trying to reinstall MySQL cause something was messed up. So now I come to the masses for some help. I have a box with cPanel/WHM on it. CentOS 5.6 64 bit. I have upgraded (through WHM) MySQL to 5.5.24 and that was successful. After some research, the options I found were an intimidating Linux command with pipes greps and dashes, and another command yum remove mysql I tried that out and it appeared to remove mysql.....ish. I tried installing MariaDB from this instructions page and it started to do it's thing and then came the zillions of errors (here's a small sample): Transaction Check Error: file /etc/init.d/mysql from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/bin/mysql_convert_table_format from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/bin/mysql_install_db from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/bin/mysql_secure_installation from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/bin/mysqlbug from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/bin/mysqld_multi from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/bin/mysqld_safe from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/bin/mysqldumpslow from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/bin/mysqlhotcopy from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/share/man/man1/innochecksum.1.gz from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/share/man/man1/my_print_defaults.1.gz from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/share/man/man1/myisam_ftdump.1.gz from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/share/man/man1/myisamchk.1.gz from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 file /usr/share/man/man1/myisamlog.1.gz from install of MariaDB-server-5.5.25-1.i386 conflicts with file from package MySQL-server-5.5.24-1.cp.1132.x86_64 So it appeared that MySQL wasn't removed correctly. I've read from different tutorials given on different sites that to install MariaDB, you had to uninstall/remove MySQL and there weren't any commands given on how to do this. Does anyone know how to "safely" remove MySQL on a WHM/cPanel server so that I can install MariaDB? Here's my repo file in case anyone needs to know... # MariaDB repository list - created 2012-07-10 17:09 UTC # http://downloads.mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/5.5/centos5-x86 gpgcheck=1

• How to read a Text File Hidden Characters?

  - by balexandre

  Hi guys, I've created a text file from an application that I developed. When I send the text file to a SYSTEM Validation, they (3rd Party System) say that the file is invalid and that the file contains 3 characters in the beginning of the file that are not allowed as well special characters are not correct. They also say I need to use either ISO 8859-1 or PC850 Well, I'm using NotePad++ and I can't see that at all! What is the best text file reader for this kinda problems? EDITED I also have a MAC and just a thought I remembered opening in TextMate ... WOW! Now I know what they are talking about! How can I have the same in Windows?

• Redirecting program errors to both log and error file

  I've a Java standalone program scheduled to run as cron at every 10 minutes I want to catch/write errors thrown by this Java program both in the log file and also as a separate error file (MyJavaStandalone.err).

• File open fails initially when trying to open a file located on a win2k8 share but eventually can su

  - by Ruddy Douglass

  Core of the problem: I receive "(0x80070002) The system cannot find the file specified" for roughly 8 to 9 seconds before it can open it successfully. In a nutshell, we have two COM components. Component A calls into Component B and asks for a UNC filename to write to - the filename returned doesn't exist yet, but the path does - it then does its work, creates and populates the file, and tells Component B its done by making another com call. At that point Component B will call MoveFile to rename the file to its "official" name. This code has worked for (literally) years. Its works fine on win2k3. Its works fine when its running on win2k8 and points to a share on a win2k3 server. It also runs fine, if the share is actually located on the same win2k8 machine that the code is running on. But if you run it on win2k8 and point it to a share on a different win2k8 server, it fails. Both Component A & component B exist in their own Windows Service running with as a domain admin account. The shares are configured for "Everyone/Full control" in all test environments, similarly so are the underlying folders that the share points to. All machines are in the same domain. During debugging I realized the file actually does exist by the time I get to checking manually for it - after several iterations it occurred to me that the file doesn't "show up" until some delay passes by - so I put in the loop below in component B as shown below: int nCounter = 0; while (true) { CFileStatus fs; if (CFile::GetStatus(tempname, fs)) break; SleepEx(100, FALSE); nCounter++; } This code does, in fact, exit and nCounter is generally between 80 & 90 iterations when it does -- indicating the file "appears" approx 8 to 9 seconds later. Once that loop exits the code can successfully rename the file and all further processing appears to work. I put a CFile::GetStatus in component A immediately before it calls into Component B and that indicates success - it can see the file and get its true size yet the call into component b made immediately after can not see the file until the above indicated delay passes. I have verified the pathnames are precisely the same, even though it would clearly have to be for the calls to eventually succeed after a pause of 8 to 9 seconds... When something like this occurs I always assume there is a bug in my code until proven otherwise, but given (a) this code has executed properly for a very long time and (other than my diagnostic loop added) has not changed, and (b) it works in all environments except the win2k8 - win2k8 share, I'm guessing there is some OS issue in here that i do not understand. Any insight would be helpful. Thanks!

  What I do: Copy an xml file (ctrl+C) on a Win Server 2008 machine. Minimize mstsc.exe (remote connection app). Paste the xml file on to my WinXP machine (ctrl+V). The result: All of the original contents are still present but another bit is appended at the end of it. E.g. the proper end of the file looks something like this: <ApplicationName>MyApp</ApplicationName> </ReceivePort> </ReceivePortCollection> <PartyCollection xsi:nil="true" /> </BindingInfo> But, after the copy, it looks like this: <ApplicationName>MyApp</ApplicationName> </ReceivePort> </ReceivePortCollection> <PartyCollection xsi:nil="true" /> </BindingInfo>al, PublicKeyToken=3zzf3xxxadyyy35" Type="1" TrackingOption="ServiceStartEnd MessageSendReceive PipelineEvents" Description="" /> <ReceivePipelineData xsi:nil="true" /> <SendPipeline xsi:nil="true" /> <SendPipelineData xsi:nil="true" /> <Enable>true</Enable> <ReceiveHandler Name="WCF_OracleDB_Rx" HostTrusted="false"> <TransportType Name="WCF OracleDB" Capabilities="779" Configuratio The extra bits it adds are things that come from earlier in the XML file. If I do the copy multiple times, the extra bits are always exactly the same but another XML file will add different lines. Extra information: If I copy/paste the file, as above, but first enclose it into a zip file I do not have the same problem. I.e. the file copies properly and without any extra surprises. If I do a copy/paste from a Windows Explorer window that's opened to the folder on the remote machine, I do not have the same behavior. I.e. the file copies properly and without any extra surprises. Question: Why does this happen?

• Corrupted .WAR file after transfer from 32-64 bit Windows Server to Desktop or vice versa

  - by Albert Widjaja

  Hi All, Does anyone experience this problem of corrupted .WAR file after it has been copied over the network share ? this is .WAR file (Web Archive) the J2EE application file (.WAR file is compressed with the same zip algorithm i think ?) Scenario 1: Windows Server 2008 x64 transfer into Windows XP using RDP client (Local Devices and Resources) Scenario 2: Windows XP 32 bit transfer into Windows Server 2003 x64 using shared network drive (port 445 SMB ?) for both of the scenario it always failed / corrupted (the source code seems to be duplicated at the end of line when you open up in the Eclipse / Java IDE). but when in both scenario i compressed the file into .ZIP file everything is OK. can anyone explains why this problem happens ? Thanks, Albert

• net use mapping not working in batch files but works in cmd

  - by Philippe

  Ok so here's the problem : I've got users using logon script in the domain (username.bat). The script simply lists 4 or 5 (net use letter: \\SERVER\directory\). However, when they open their session, the logon script doesnt work and returns system error 53 or 67 for all of them. I tried running the script after the profile has loaded and evrything is running, and it still gives me the error. I've then tried to run the same command in the cmd.exe. Everything mapped correctly. It also works fine if I map the drives using the "Tools Map network drives" utility. Is there anything that can prevent a command to work when ran in a batch-file but works correctly when typed in manually?

• File open fails initially when trying to open a file located on a win2k8 share but eventually can su

  - by Ruddy Douglass

  Core of the problem: I receive "(0x80070002) The system cannot find the file specified" for roughly 8 to 9 seconds before it can open it successfully. In a nutshell, we have two COM components. Component A calls into Component B and asks for a UNC filename to write to - the filename returned doesn't exist yet, but the path does - it then does its work, creates and populates the file, and tells Component B its done by making another com call. At that point Component B will call MoveFile to rename the file to its "official" name. This code has worked for (literally) years. Its works fine on win2k3. Its works fine when its running on win2k8 and points to a share on a win2k3 server. It also runs fine, if the share is actually located on the same win2k8 machine that the code is running on. But if you run it on win2k8 and point it to a share on a different win2k8 server, it fails. Both Component A & component B exist in their own Windows Service running with as a domain admin account. The shares are configured for "Everyone/Full control" in all test environments, similarly so are the underlying folders that the share points to. All machines are in the same domain. During debugging I realized the file actually does exist by the time I get to checking manually for it - after several iterations it occurred to me that the file doesn't "show up" until some delay passes by - so I put in the loop below in component B as shown below: int nCounter = 0; while (true) { CFileStatus fs; if (CFile::GetStatus(tempname, fs)) break; SleepEx(100, FALSE); nCounter++; } This code does, in fact, exit and nCounter is generally between 80 & 90 iterations when it does -- indicating the file "appears" approx 8 to 9 seconds later. Once that loop exits the code can successfully rename the file and all further processing appears to work. I put a CFile::GetStatus in component A immediately before it calls into Component B and that indicates success - it can see the file and get its true size yet the call into component b made immediately after can not see the file until the above indicated delay passes. I have verified the pathnames are precisely the same, even though it would clearly have to be for the calls to eventually succeed after a pause of 8 to 9 seconds... When something like this occurs I always assume there is a bug in my code until proven otherwise, but given (a) this code has executed properly for a very long time and (other than my diagnostic loop added) has not changed, and (b) it works in all environments except the win2k8 - win2k8 share, I'm guessing there is some OS issue in here that i do not understand. Any insight would be helpful. Thanks!

• File Not Found error launching Guest OS in a non-administrator user account

  - by ToreTrygg

  Hi, I am running Fusion 2.0.6 (196839) on an iMac running 10.6.2 with 3 user accounts (1 Administrator). I have Fusion set up to share the Guest OS, and it's been working splendidly for nearly a year. Within the Guest OS (Windows XP PRO), there are also 3 user accounts (1 Administrator). Last night I went to back up my VM to an external drive, and to minimize the file size and transfer time, I deleted all Snapshots but the most-recent one. I then backed up the VM externally (28.23 GB). Today, one of my users tried to launch the Guest OS from within her user account, and received the following error message: "File Not Found: Windows XP Pro-000006.vmdk "This file is required to power on this virtual machine. If this file was moved, please provide its new location." My two choices are Cancel and Browse. When I browse, I can locate the Windows XP Pro-000006.vmdk file, which appears to be contained within the VM file (Windows XP Pro.vmwarevm). However, it still won't launch from a non-Admin user account. If I view the package contents of the VM file from the user account, the above file is present and appears to be created upon each launch of the Guest OS. If I go back to my Administrator account on the Mac and then launch Fusion, the Guest OS works perfectly for all 3 user accounts within XP Pro. I have tried to delete the Guest OS from Fusion's Library within the problem user account, then re-connect it to that Library, but the result is the same. The Guest OS data integrity is 100% -- but is accessible only from the OS X Administrator account. This problem only surfaced after deleting several older Snapshots. Again, the data is there, the Guest OS powers up normally in the Mac's Administrator account, but persistently returns the above error when attempting to power on from a non-Admin account on the Mac. I'm not sure how this is affecting the error, but when I look at Hard Disk Settings, the "unable-to-locate" file is the filename of the virtual HD. I don't want to make any changes to my (working) VM without any advice from the knowledgeable people on this forum. Any help will be greatly appreciated, thanks!

  - by JimDel

  Does anyone know what happens to a PDF file when you save it as a static PDF file? I have a 17K PDF file that doesn’t work will with my software. But when I save it as a Static PDF using Adobe Live Cycle, the file works just fine. But it’s significantly larger (327K). Because these file will be download over the web, I really want to keep the size down. I have hundreds of files like this. If I knew what happens to the file when it’s converted I might be in better shape. Thanks

• How to convert eps file to a large jpeg image

  - by Anand

  Hello, I am using Linux. I want to convert an eps file to jpeg file. I find that I can use "convert" command. However, the resulting image looks very small. I want to enlarge the jpeg file by -resize option. It seems not to work. The resulting image is a pure black one. Do anyone has the same problem? Here are more details: 1: if I use convert -scale 1000x1000 your.eps your.jpg the resulting image looks like a low quality image. The eps vector image is not scaled properly. 2: if I use convert -geometry 300% your.eps your.jpg I get a pure black image. Here is my phf file: 2shared.com/document/RXl2Be-g/askquestions.html and my eps file: 2shared.com/file/qrmwKegj/askquestions.html Thank you very much for your help!

• Nginx no longer servers uwsgi application behind HAProxy - Looks for static file instead

  - by Ralph

  We implemented our web application using web2py. It consists of several modules offering a REST API at various resources (e.g. /dids, /replicas, ...). The API is used by clients implementing requests.py. My problem is that our web app works fine if it's behind HAProxy and hosted by Apache using mod_wsgi. It also works fine if the clients interact with nginx directly. It doesn't work though when using HAProxy in front of nginx. My guess is that HAProxy somehow modifies the request and thus nginx behaves differently i.e. looking for a static file instead of calling the WSGI container. Unfortunately I can't figure out what's exactly going (wr)on(g). Here are the relevant config sections of these three component's config files. At least I guess they are interesting. If you miss anything, please let me know. 1) haproxy.conf frontend app-lb bind loadbalancer:443 ssl crt /etc/grid-security/hostcertkey.pem default_backend nginx-servers mode http backend nginx-servers balance leastconn option forwardfor server nginx-01 nginx-server-int-01.domain.com:80 check 2) nginx.conf: sendfile off; #tcp_nopush on; keepalive_timeout 65; include /etc/nginx/conf.d/*.conf; server { server_name nginx-server-int-01.domain.com; root /path/to/app/; location / { uwsgi_pass unix:///tmp/app.sock; include uwsgi_params; uwsgi_read_timeout 600; # Requests can run for a serious long time } 3) uwsgi.ini [uwsgi] chdir = /path/to/app/ chmod-socket = 777 no-default-app = True socket = /tmp/app.sock manage-script-name = True mount = /dids=did.py mount = /replicas=replica.py callable = application Now when I let my clients go against nginx-server-int-01.domain.com everything is fine. In the access.log of nginx lines like these are appearing: 128.142.XXX.XX0 - - [23/Aug/2014:01:29:20 +0200] "POST /dids/attachments HTTP/1.1" 201 17 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" 128.142.XXX.XX0 - - [23/Aug/2014:01:29:20 +0200] "POST /dids/attachments HTTP/1.1" 201 17 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" 128.142.XXX.XX0 - - [23/Aug/2014:01:29:20 +0200] "POST /dids/user.ogueta/cnt_mc12_8TeV.16304.stream_name_too_long.other.notype.004202218365415e990b9997ea859f20.user/dids HTTP/1.1" 201 17 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" 128.142.XXX.XX0 - - [23/Aug/2014:01:29:20 +0200] "POST /replicas/list HTTP/1.1" 200 5282 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" 128.142.XXX.XX0 - - [23/Aug/2014:01:29:20 +0200] "POST /replicas/list HTTP/1.1" 200 5094 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" 128.142.XXX.XX0 - - [23/Aug/2014:01:29:20 +0200] "POST /replicas/list HTTP/1.1" 200 528 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" 128.142.XXX.XX0 - - [23/Aug/2014:01:29:21 +0200] "GET /dids/mc13_14TeV/dids/search?project=mc13_14TeV&stream_name=%2Adummy&type=dataset&datatype=NTUP_SMDYMUMU HTTP/1.1" 401 73 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" 128.142.XXX.XX0 - - [23/Aug/2014:01:29:21 +0200] "POST /replicas/list HTTP/1.1" 200 713 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" 128.142.XXX.XX0 - - [23/Aug/2014:01:29:21 +0200] "POST /dids/attachments HTTP/1.1" 201 17 "-" "python-requests/2.3.0 CPython/2.6.6 Linux/2.6.32-358.23.2.el6.x86_64" "-" But when I switch the clients to go against HAProxy (loadbalancer.domain.com:443), the error.log of nginx shows lines like these: 2014/08/23 01:26:01 [error] 1705#0: *21231 open() "/usr/share/nginx/html/dids/attachments" failed (2: No such file or directory), client: 128.142.XXX.XX1, server: localhost, request: "POST /dids/attachments HTTP/1.1", host: "loadbalancer.domain.com" 2014/08/23 01:26:02 [error] 1705#0: *21232 open() "/usr/share/nginx/html/replicas/list" failed (2: No such file or directory), client: 128.142.XXX.XX1, server: localhost, request: "POST /replicas/list HTTP/1.1", host: "loadbalancer.domain.com" 2014/08/23 01:26:02 [error] 1705#0: *21233 open() "/usr/share/nginx/html/dids/attachments" failed (2: No such file or directory), client: 128.142.XXX.XX1, server: localhost, request: "POST /dids/attachments HTTP/1.1", host: "loadbalancer.domain.com" 2014/08/23 01:26:02 [error] 1705#0: *21234 open() "/usr/share/nginx/html/replicas/list" failed (2: No such file or directory), client: 128.142.XXX.XX1, server: localhost, request: "POST /replicas/list HTTP/1.1", host: "loadbalancer.domain.com" 2014/08/23 01:26:02 [error] 1705#0: *21235 open() "/usr/share/nginx/html/dids/attachments" failed (2: No such file or directory), client: 128.142.XXX.XXX, server: localhost, request: "POST /dids/attachments HTTP/1.1", host: "loadbalancer" 2014/08/23 01:26:02 [error] 1705#0: *21238 open() "/usr/share/nginx/html/replicas/list" failed (2: No such file or directory), client: 128.142.XXX.XXX, server: localhost, request: "POST /replicas/list HTTP/1.1", host: "loadbalancer.domain.com" 2014/08/23 01:26:02 [error] 1705#0: *21239 open() "/usr/share/nginx/html/dids/attachments" failed (2: No such file or directory), client: 128.142.XXX.XXX, server: localhost, request: "POST /dids/attachments HTTP/1.1", host: "loadbalancer.domain.com" 2014/08/23 01:26:02 [error] 1705#0: *21242 open() "/usr/share/nginx/html/replicas/list" failed (2: No such file or directory), client: 128.142.XXX.XXX, server: localhost, request: "POST /replicas/list HTTP/1.1", host: "loadbalancer.domain.com" 2014/08/23 01:26:02 [error] 1705#0: *21244 open() "/usr/share/nginx/html/dids/attachments" failed (2: No such file or directory), client: 128.142.XXX.XXX, server: localhost, request: "POST /dids/attachments HTTP/1.1", host: "loadbalancer.domain.com" As you can see, that request looks the same, only the client IP changed, from the client's host to the one from loadbalancer.domain.com.

I searched the web for multiple hours already, but without much luck so far. Any help is very much appreciated. Cheers, Ralph

• Running a defect php file cause error 500

  - by John Brunner

  When I address a PHP file, I always get an error 500. I've looked up the logs of my Apache server, and this displays that some includes etc. in the PHP file address files which don't exist on the server. They don't exist because I'm just testing my PHP file. But could it be achieved that the server runs the php file in every case, even when something is wrong? Every 30 seconds an entry is made in the error_log file which says [Sat Jun 09 17:55:07 2012] [error] [client 10.224.55.160] File does not exist: /var/www/html/index.html ... but there IS an index.html?!
